\FRANKL'IN o. rronnmn, or PUEBLO, COLORADO.

To all whom it may concern:

Be it known that I, FRANKLIN C. Hon- MAN, a citizen of the United States of America, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented a new. and useful Improvement in Power Plants, of which the following'is a specifi cation.

The present invention relates to an 1m'- proved power plant involving. the use of an external source of power as an automobile or auto-truck, and the invention is designed for thepurpose of providing a power lant adapted for use on farms and in other places whereby "power may be developed and lllllllizedfor avariety of purposes;

The invention 'conslsts. essentially in the portable apparatus adapted to be"0perate d.

by the drivin'g wheels of an automobile to transmit power to the 'des redr-pomt of ap plication, and in 'certain'novel combinations and arrangements of parts as will behere after more fully pointed out and claimed.

Inthe accompanying drawings I have illustrated'one complete" example of the phys1- cal embodiment of my invention constructed accordingtothe'best mode I haveflso far devised for thepractical application of' the J principles of my invention.

Figure 1 is a top plan view of a structure embodying m invention.

Fig. 2 is a ont view of the apparatus.

Fig. 3 is a view of reduced scale show ng the apparatus when an automobile is being brought into or taken out of operative position with the apparatus.

Fig. 4 is a similar view showing the autotruck in operative position on the apparatus.

In the preferred embodiment of my 1nvention as depicted in the drawings, the power plant is portable and of convenient size and shape to accommodate it for use in connection with a typical automobile or auto-truck, and for convenience of illustration I have utilized a medium size autotruck 3mm PLANT.

each formed with a sharpened point or apex.

6 and secured to the side bars by meansof bolts or other suitable fastening members tohold the fulcrum blocks rigid. v

Upon the supporting base and suspended from the two fulcrum blocks is a tiltable or oscillatable frame rectangularin shape and involving in its structure a pair of" side trusses as 7 and 8 which are joined atapf proximately their centersby a transverse cross bar or brace9. The angle irons 10' are employed to secure the upper and lower the fastening the parts together.

bars "of the trusses and bolts 11 are used means for rigidly attaching -:At thefundersidebf each of the side trusses is arranged a fulcrum plate112, bolt-f ed to the truss and fashioned with ,a ce'ntralnotch 13 which fits over theapex of the fulcrum blocks so that the frame may oscil late on the fulcrum blocks, and rest'at its all Jcl heiskids perform a double function as illustrated in Figs. 3 and 4, where in the former figure the rear driving wheels 17 of the auto-truck 18 have been driven up on the frame passing over the skid, and in Fig. 4 the skid is in use as a brace to the frame, holding it rigidly in its position and preventing downward movement of the front end of the tiltable frame.

Across the rear of the frame a sectional knockdown driving shaft 19 extends, and is journaled in bearings 20 bolted to the upper side of the side trusses, and the shaft is provided with a small pulley wheel 21 and the larger drive pulley 22, which may .be connected as by belt 23 in dotted lines Fig. 4 to transmit power from the driving shaft to its desired destination. When being transported the trusses and shaft are disjointed so that the separated parts may be moved with facility.

A small pulley 24 is'carried by the drivin shaft, and this pulley together with pu ley 21 is connected, as by belts 25 and 26 to a pair of complementary wheels 27 and 28 on stud shafts 29' and 30, journaled in bearings 31 at the front end of the side trusses of the tiltable frame.

. The stud shafts are of sufiicient length to accommodate the idle pulleys in order that the spacebetween the side trusses atthe front may be clear and unobstructed 'in order to accommodatethe mechanism at the Y underside of the auto-truck. The construction of the skid brace also allows rowan obstructed movement of the auto-truck as seen in Flgz'a The two friction belts 25 and 26 are of sufficient width, to accom inodate the two rear drivingwheels of the automobile, and, in use, with the apparatus as in Fig. 5, the; automobile is backed, upon the frameiwith its rear or driving Wheels traveling over the two belts 25 and 26, and it Will readily be seen that as soon 'as, the weight of lthe truck. passes over the center a of, the'tiltable frame, the" frame will be tiltedback to the position; ofKFig. iresting upon the crossbra'cefl ofthe base. The rear wheels of theautomobile are now cradled or seated ina depression 32 with the Weight of the wheel carried inpa'rt pulley Wheels-onthe' driving shaft, and when the motor of the;

automobile is i1i"o1: e-ration1the nci ement the automobile wheels is transmitted directly to thefriction belts and 'so to the driying;

shaft and pulley and belt.

Thebr'a'ce-skid 16ho1ds' the frame jin rigid position b as in Fig, 4, but 'w'hen it is desired to'displa'e the automobile, the skidis utilizfed asli'n Figl 3 and the'automobile is run down off the frame as shown'therein,

From the above description taken in conmotion "with my drawings it is evident that copies of this patent maybe obtained as Washington, '1). 0?
